我知道this page列出了基于 Nitro 系统的实例类型，但我想使用 CLI 以动态方式了解该列表。 (例如，使用aws ec2描述实例)。除了解析静态页面之外，是否可以获得基于 Nitro 的实例类型？如果是的话，你能告诉我怎么做吗？
最佳答案
您必须编写一些额外的代码才能获取该信息。 aws ec2 describe-instances 将为您提供 InstanceType 属性。您应该使用编程语言来解析 JSON，提取 InstanceType，然后调用 describe-instances，如下所示: https://docs.aws.amazon.com/cli/latest/reference/ec2/describe-instance-types.html?highlight=nitro
从您返回的 JSON 中提取虚拟机管理程序。如果实例是 Nitro，这将为您提供 Nitro。
这是一个可能有效的 Python 代码。我尚未对其进行全面测试，但您可以对其进行调整以获得您想要的结果。
